Deep Spectrum Cartography: Completing Radio Map Tensors Using Learned Neural Models [PDF]
IEEE Transactions on Signal Processing, 2021 The spectrum cartography (SC) technique constructs multi-domain (e.g., frequency, space, and time) radio frequency (RF) maps from limited measurements, which can be viewed as an ill-posed tensor completion problem.

On Developing Techniques for Sharing Satellite Spectrum with Indoor Small Cells in 5G
Energies, 2020 In this paper, we present two spectrum sharing techniques for a multisystem, incorporating an integrated satellite-mobile system and an autonomous terrestrial-mobile system (iSMS/aTMS), namely orthogonal spectrum sharing (OSS) and non-orthogonal spectrum
